Thursday's weather: fog and a little sun

The weather pattern over the next several days will remain largely uninterrupted, but a major pattern change is on the way that should offer new writing material for weather forecasters.

For now, it's looking like another mostly cloudy day across the region with morning clouds and fog. As has been the case, afternoon sunshine will be spotty but present for most communities. High temperatures will top out in the low to mid-50s.

Bigger changes arrive toward the end of the weekend, as a chilly arctic high will begin to filter out of the Gulf of Alaska, slide along British Columbia until it eventually veers east of the Rockies. What this means for our region is a trusty northerly flow, which will help scour out all the clouds and fog. It also means much cooler high temperatures, but we'll get into those specifics Friday.

Needless to say, I think we've found the trick to removing days and days of fog and low clouds. Arctic highs are chilly, but at least they're clear and dry.
